- Got commissioned for an item. Got $100 payment down on a $300 commission
- Finished item, and due to an unrelated circumstance, got the same amount the commissioner owes me ($200) from the commissioner.
- Over a month goes by before the commissioner decides they want that amount back, and now no longer wants the finished item. They're threatening to take me to court if I don't give them money instead. They still refuse to pick up the item, which I currently have in my possession.
Nothing is wrong with the item, they just want the money back instead, despite the item being finished. It's like going to your job, working for an entire week, then your boss tells you "Nah I want to use the money on something else, so I'm not paying you for all that work and time you did."
